Alarm Information

Over Temperature Alarm

When the temperature of the PA module exceeds the normal range, the Alarm Indicator

will glow red and the LCD display will give you the prompt message below:

Then the repeater will stop transmitting, and you need to:

1. Check whether the Fan Failure Alarm prompt message appears on the LCD display.

If yes, refer to measures taken in Fan Failure Alarm.

2. Check whether ambient temperature and ventilation conditions satisfy the foregoing

installation requirements. If not, please make improvements as soon as possible. For

example, install more air conditioners for optimal ventilation.

3. Check if the RF cable or antenna feeder that is connected to the transmitter is loose or

damaged. Poor connection between them could cause high TX power. If yes, secure or

replace the cable or antenna feeder.

4. If the above measures fail to solve the problem, contact your local dealer for technical

support.

When repeater temperature falls into normal range, the prompt message will disappear

and the Alarm Indicator will go out.
